  Sorry, you have problems getting your patches installed. I have a number of things for you to look at.  First of all, your Background Intelligent Transfer Services set to Automaticand started and Windows Update ? You can check these settings by typing services.msc in the search box of the start menu.

  Since they are all Office updates, you can do a repair for office function.  To do this, click the Start button, type programs and features and click the enter key. Right click on Microsoft Office 2007 and choose change.  Choose fix and continue.  Microsoft Office will attempt to fix any problems there (this will) take a few minutes to run.

  Sometimes in order to get patches to install correctly, you must perform these tasks manually.  Download and run each patch:

  KB980729

  KB981715 

  KB976321

  One last thing, you mention that you removed Norton.  Did you use just add/remove programs?  If so, you must run the Norton Romoval Tool (from Norton). Add/Remove Programs does not receive everything uninstalled.  Here is the link: ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

  Hope this helps to get your installed patches.
